Answer:
QR ≈ 16.3
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
57 QR = 926.9 ( divide both sides by 57 )
QR ≈ 16.3 ( to the nearest tenth )
Answer:
Step-by-step explanation:
Given the figure of a square pyramid
The area pf the base =area of the square of side 14 in =
the area of the sides = 4 times the area of a triangle of a base of 14 in and a height of 12 in
so, the area of the sides =
So, the surface area of the pyramid =
So, the answer will be A = 532 in^2
